SASH. STRUCTURE.

Specification of Letters Patent. Pateflted M-ar. 14;, 1911.

Application filed November 18,1909, Serial No. 528,697.

To all whom it may concern:

Be it known that I, .Ennns'r M. BAKER, a citizen of the United States, residing at Detroit, county of Wayne, State'of Michigan, have invented a certain new and useful Improvementin Sash Structurea'and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which forma part of this specification.

This invention relates toa sash adapted to hold glass or tile, and has for its object an improved construction of metal sash arranged to produce a symmetrical cross shaped figure on the flanged 'side of said sash, and a symmetrical cross shaped figure on the webbed side of said sash with the parts interlocking,and so locked together as to be strong, durable and extremely neat in appearance.

The sash structure is made from T iron in which the cross part-of the T is poncaved or coved on each side of the axis and the two arms of the T form a seat for the sides of the sheet of glass, while the web, which projects from the two arms and forms the stein of the T forms a bearing for the vedges of the glass.

In the drawings :Figure 1, shows a fin ished joint. Fig. 2, is a side elevation of one member used in making a finished joint. Fig. 3, is a side elevation of the second member used in making a finished joint. Fig. 4, is a cross section on the line 4-4 of Fig. 1. Fi 5, shows a process in construction of the pint. Fig. 6, shows across sec-- ti'on.

The T iron A of Fig. 2 is punched through the flange 1 and through a part of the web" 2 to produce an opening 3 that corresponds as nearly as possible with the cross section of the flange, and of about half of the web. The T iron of the member 3 is punched with a n'otch & to engage over that part of the web 2 which lies between the bottom of the opening 3 and the edge Mel-the member.

The member of Fig. 2'istl'ie'n bent to spread theupper boundaries 7 and 8 of the opening" 3, which are spread only sufficiently to enable the member 13 to. he slipped into or insorted into the opening '3 with theslot 4 engaging over the web 2. The member A is then straightened, reshaping the opening.

3 to its original shape over the now inclos'e member B. The obverse or flanged side of the sash is now symmetrical in appearance at the joint with the apparent meeting faces of the incurved surface-0f the flange divergplane.

both lie-in the same plane.

What I claim is g y An interlocked metallic structure for sashes and the like comprising two bars crossing each other, each of said bars being provided with a web and a flanged'head, the baseof which is relatively wider than the top thereof, the flanged head of one of said bars being severed and a part there of removed to produce an opening corresponding to the cross section of the flanged head of the other bar, and the portion of the web of said first bar underlying the open? ing formed in the head thereof being proing from what is substantially a common center at 12 and the faces are in the same The obverse side presents the same uniform appearance, and the surface -of for substantially half its depth, the web of the crossing bar being provided with a notch extending upwardly from the lower edge thereof for substantially half its depth, the webs of the two bars being halved together and crossing one another and the flanged head of one bar passing through-the opening formed in the flanged'head of the other bar.

In testimony whereof, I sign this specification in the presence of two witnesses.
